Window pet doors are a versatile and non-invasive solution for pet owners who want to offer their pets the freedom to come and go at their will. Window pet doors are easy-to-install doors that fit neatly into both sash windows that slide vertically and sliding windows that move horizontally. This compatibility with different window types makes these pet doors adaptable to a variety of home layouts.
The installation process is designed with homeowners in mind - many of these pet doors can be set up within 60 seconds, and require no tools or alterations to your window. Made from durable materials like sturdy aluminum and vinyl, these doors are crafted to withstand frequent use and fit any window frame, ensuring a seamless fit with your home's aesthetics.
Window pet doors are offered in a range of styles to meet diverse pet and homeowner needs. From manual flaps to electronic flaps, pet owners can choose a door that best matches their pet's habits and their own preferences. Electronic flaps provide an added layer of security, only permitting access to pets wearing a corresponding microchip or collar tag. This feature prevents uninvited animals from gaining entry, keeping your home secure.
Security-conscious homeowners can opt for models that include additional locking mechanisms. These mechanisms can secure the pet door as needed, such as during times when you're away from home.
To combat the elements and ensure your home stays comfortable throughout the year, many models are weather-resistant and offer excellent insulation. Higher-end models also promise energy efficiency, which can lead to substantial savings on heating and cooling expenses over time.
Whether you are a cat or a dog owner, there are window pet doors to match all pet sizes and homeowner requirements. And for any questions or advice on product selection, customer service teams stand ready to assist.
Invest in a window pet door today, and enjoy the peace of mind that comes with providing your pet the freedom they deserve, all without compromising the security or aesthetics of your home.
ALUMINUM VS. VINYL PANELS
How to Determine if Your Window Frame is Vinyl or Aluminum:
- Tap the frame: An aluminum sliding window will sound metallic while a vinyl one will make a dull, plastic noise.
- Measure Track Width: Vinyl tracks are often slightly wider than aluminum. Aluminum tracks are generally 1” wide while vinyl tracks are about 1.5” wide.
Aluminum Panels: Aluminum Dragon panels fit aluminum windows with tracks at least 1” thick. They will fit vinyl windows with tracks at least 1” thick too. However, since vinyl doors generally have wider tracks the panel may wobble a bit.
Vinyl Panels: The Dragon Vinyl Panel is designed to fit in vinyl-framed windows with tracks at least 1” thick. The vinyl pet door panel framing will match your existing window for an aesthetic look. Vinyl is also excellent for cold weather, as it resists the “sweating” (condensation buildup) that aluminum can be prone to in cold climates.
How to Measure Track Width
You’ll need to measure your window track to choose the correct pet door panel height. Make sure to measure the track thickness, which needs to be at least 1” to accommodate the panel.
Measure Track Width for Sash Windows: For sash windows, measure from the deepest point of one side of the track all the way to the deepest point of the other side of the track to find the track width.
Measure track Width for Side-Sliding Windows: To measure your track height, use a tape measure to find the distance from your bottom track to your upper track.

Locking & Security
All Dragon Pet Door models come with a sturdy thermoplastic Locking Cover to block access to the pet door as needed. The locking cover keeps neighborhood critters out of your home and allows you to lock the flap at night or when you’re away.
Locking Side-Sliding Window Panels: Dragon sideways-sliding window inserts come with a clamp lock that attaches to the flange of the window track at the edge of the sliding window panel. This clamp securely locks the window to prevent access while you’re away. When you want to open your window, simply remove the clamp lock. For additional security, we recommend a wooden dowel or Charley Bar. The Charley Bar can be unlocked in a matter of seconds to open your sliding window.
Locking Sash Window Panels: To permanently lock your Dragon sash, you can install wood screws in the track immediately above the window on both sides. With this method, you would no longer be able to raise the window. For continued use of your window sash, the Charley Bar is the perfect solution. It unlocks in just a few seconds so you can access the sash window.

How to Measure Your Pet
Measuring your pet is crucial to choosing the right door for your pet’s safety and comfort. To find your dog’s shoulder height measure from the floor to the top of their withers. The step-over height should be as low as possible for comfortable use by your pet, especially as they grow older. You can use the formula below:
Step Over + Flap Height = At least 1" Taller than Your Dog’s Shoulder Height.
